Filedialog impossible to use with keypad navigation

QFileDialog contains own internal derived classes for line edit and
list view. Unfortunately, these classes do not handle keypad navigation
correctly - they just accept the navigation key events, causing the
navigation to halt.

Added support for QFileDialogListView, QFileDialogTreeView and
private filedialog class QFileDialogPrivate to handle and possibly ignore
keypad navigaion key events.

Additionally, added support to keypad navigation to ignore empty
widgets. This allows keypad navigation not to go invisible when empty
widgets are tried to be navigated into.
